Most animal cells are bathed in an isotonic fluid, such as blood, which protects them from bursting. how does an isotonic solution protect a cell from bursting?

a. it is a solution that has no solutes, making it an empty fluid.

b. the concentration of solutes is equal on both sides of the cell, so the water doesn't rush in.

c. it is a solution with a concentration of solutes higher on one side of the cell than the other.
